4-FACE FUEL INSPECTION

FOUR SIDED FUEL INSPECTION
4-FACE FUEL INSPECTION

The 4-Face Fuel Inspection is performed during regular offload in a PWR to find failed fuel. A system of four HD cameras mounted on a frame is placed above the upender to record a video of all four sides and the bottom nozzle of each fuel assembly passing by. This gives an immediate verification of fuel assembly integrity, without affecting the critical path.

Applications

  • Quad-side fuel inspection during regular offload, without affecting the critical path
  • 5th camera or tilt function for bottom nozzle inspection
  • Customer adapted turnkey system with HW, SW, installation and commissioning, ready for use
  • Custom built 4-face fuel inspection software included featuring video recording, playback of recorded files, slow motion in playback mode, text and audio input in recorded files and image measuring

Benefits

  • Inspection of all four sides and bottom nozzle of fuel assemblies simultaneously
  • Extensive zoom capabilities, x10 optical x10 digital, facilitate to find fuel failures
  • Monitor can shift between one-side or quad-side mode, showing either one side of the fuel or all four sides at the same time
  • Additional software available, e.g. bow measurement software for instant calculation of bending of fuel assemblies
  • Possibility to stream video over the NPPs computer network
  • Proven functionality; more than 25 4-face systems installed world-wide
